Dialyzer forgot to stop a server process before finishing its analysis.
This is a concurrency error detected by Concuerror.

The compiler would silently accept and Dialyzer would crash on
code like:
<<X:(2.5)>>
It is never acceptable for Dialyzer to crash. The compiler should
at least generate a warning for such code. It is tempting to let
the compiler generate an error, but that would mean that code like:
Sz = 42.0,
<<X:Sz>>.
would be possible to compile with optimizations disabled, but not
with optimizations enabled.
Dialyzer crashes because it calls cerl:bitstr_bitsize/1, which
crashes if the type of size for the segment is invalid. The easiest
way to avoid that crash is to extend the sanity checks in v3_core
to also include the size field of binary segments. That will cause
the compiler to issue a warning and to replace the bad binary
construction with a call to erlang:error/1. (It also means that
Dialyzer will not issue a warning for bad size fields.)

Xref now accepts filenames with character codes greater than 126.
(Thanks to Emile Joubert for reporting the issue.)

* hb/dialyzer/typesig_solver_v2/OTP-10110:
Add an undocumented option [--solver [v1 | v2]]
Add an alternative implmentation of the typesignature solver
|
|
The original implementation of the type signature solver is called 'v1'
and the newly introduced alternative implementation is called 'v2'.
It is possible to run just the one of the solvers (in case there is a
bug in for instance the v2 implementation) or both solvers
("--solver v1 --solver v2"). In the latter case an error is thrown if
the outcome differ.
|
|
An alternative implementation of the solver in dialyzer_typesig has
been introduced. It is faster than the original implementation.
Note: there is code for "loop detection". Where a loop occurs, the
evaluation is stopped and the current solution returned. This
behaviour is consistent with how the original implementation works.
There are a few known cases where the loop detection kicks in. They
are due to bugs which will hopefully be fixed in a near future.

Due to various operating systems (in both the DTrace and SystemTap
worlds) not fully supporting DTrace probes (or SystemTap-compatibility
mode probes) in shared libraries, we relocate those probes to the
statically-linked virtual machine. This could be seen as pollution
of the pristine VM by a (yet) experimental feature. However:
1. This code can be eliminated completely by the C preprocessor.
2. Leaving the probes in the dyntrace NIF shared library simply
does not work correctly on too many platforms.
*Many* thanks to Macneil Shonle at Basho for assisting when my
RSI-injured fingers gave out.
Tested on:
* CentOS 5, SystemTap 1.3
* Solaris 10 (note)
* Solaris 11
* OpenIndiana 151
* SmartOS 20120809T221258Z
* FreeBSD 9.0-RELEASE (note)
I had hoped to be able to test CentOS 6 + SystemTap 1.7, but the
details of dealing with all dependencies for a 2.6.32-279.5.1.el6.x86_64
kernel are too time consuming right now.
(note: Solaris 10 and FreeBSD 9.0-RELEASE can take a long time to compile)

When opening a connection, the connection process would link itself to
ct_util_server before calling the init callback, e.g. in ct_netconfc,
ct_telnet etc. If the init callback failed, then ct_util_server would
get the 'EXIT'. ct_util looks up the pid in the connection table, but
since the connection is not yet registered it is not found. ct_util
does not know which process it is and will thus die - aborting the
complete test run.
This commit moves the link(CtUtilServer) after the init callback, so a
crash in the init callback will not be detected by ct_util_server -
the caller process, however, will get a 'DOWN' message due to
monitoring and ct_gen_conn:start will give an error return.
|
|
Earlier, it was possible to open connection (ct_gen_conn) with the
same (required) name twice, which could give unexpected results. Such
attempts will now return {error,{connection_exists,OtherClient}}.
|
|
Earlier ct_util_server would terminate and thus abort the complete
test run if a connection process (ct_gen_conn) crashed. This is now
changed so that ct_util will only print an error report (in the test
case log) and continue the rest of the test.

The netconf client supports basic netconf functionality over SSH. In
order to allow testing of both success and failure cases, it is
intentionally written to allow non-standard behavior.
In order for the netconf client to use the generic connection
mechanism in common_test, ct_gen_conn has been updated to be more
flexible:
Added options:
{reconnect,bool()}
{forward_messages,bool()}
{use_existing_connection,bool()}
Allow handle_msg to return
{reply,Reply,State} |
{noreply,State} |
{stop,Reply,State}
If forward_messages==true, the ct_gen_conn callback must also
implement:
handle_msgs(Msg,State) -> {noreply,State} | {stop,State}

Release_handler_suite correctly checks that no calls to the file module
is done during a diskless upgrade, but file:native_name_encoding is
a BIF that does no real i/o and can therefore be called during command line

Commit df8e67e203b83f95d1e098fec88ad5d0ad840069 broke
"./otp_build update_primary" because epp:parse_file/4 was
added and used from the compiler, but the epp module is not part
of the primary compiler that is used to compile the bootstrap
compiler. Fix the problem by including the epp module in the
primary compiler.
